Show transcript0:33Look around you.0:41Look around you.0:48Just look around you.0:54Have you Have you worked out what we're looking for?0:58Correct. The answer is water.1:05This program, water, is discussed in chapter 1 of your textbook, which accompanies this series.1:15Please ensure that you have your copy book at hand, as you'll be asked to take down notes from the screen at various points throughout the program.1:24Water. Delicious, refreshing water.1:30From ocean to sea to lake to pool to pond to puddle to drop to drip.1:38Water, chemical symbol H20, is all around us. It's the giver of life, and it's there with us from our first cup of tea in the morning to our nightly Bithuvik.1:53But what is water? It's a difficult question because water is impossible to describe.1:59One might ask the same about birds. What are birds? We just don't know.2:08But we do know that water is the most powerful substance on Earth, and whatever form it's in, be it ice,2:17vapor,2:19or just water, it has the capacity to affect whatever it comes into contact with.2:28Ruined.2:31Experiment 1.2:35An experiment was carried out to demonstrate the effects of boiling water upon proteins.2:43A quantity of water is heated over a Bunsen until it reaches its boiling point of 1000 degrees.2:53Now we take our sample of protein.2:57For the purposes of this experiment, we are using an egg.3:04Next, the egg is placed carefully into the beaker.3:10Let's see what happens to the egg after it's been in the boiling water for 1 minute.3:21The scientist removes the egg and examines its interior.3:30From the state of the albumen, we can see that the protein has hardly reacted to the intense heat of the water.3:39Let's try another egg, this time for 2 minutes.3:58Make sure you look out for the release of the new albumen. It's out now.4:07The protein is beginning to react.4:12We try a further egg, this time for 3 minutes.4:30Now let's take a look inside the third egg.4:34The heat of the water has caused the molecular structure of the glutenous protein to coagulate.4:42In other words, not too runny, not too hard, a perfect eggy.4:48Salt is added to taste, and breakfast is served. La petit déjeuner est prêt.4:59Write that down in Your copy book now.5:07When rain freezes, it becomes snow.5:13Snow's main use, of course, is for entertainment.5:18Here's a modern snowman.5:22Batteries have been used for the eyes, an aerial for the nose, and a calculator for the mouth.5:30Hello.5:32Hello.5:34But it's not just man that uses frozen water.5:41These ants have been trained to design and build an igloo using tiny blocks of ice.5:58Once the igloo is complete, the ants take a well-deserved rest.6:04We'll come back to the ants later. In the meantime, thanks, ants.6:10Thants.6:15Experiment 2.6:18An experiment was carried out to determine the effects of nitrogen gas upon water.6:24First, a sample of water was taken.6:31Next, a Jane Grey's pipe is fitted to the nozzle of a canister of nitrogen.6:41The Jane Grey is placed in the beaker of water.6:47We're using about 10 pence worth of gas.6:54Now we turn on the canister to release nitrogen.7:01The gas methipulates gently through the Jane Grey and into the water, causing bubbling.7:08The methipulation is allowed to continue for 5 minutes.7:14When the time is up, we turn off the gas and free the Jane Grey from the beaker.7:29Now let's take a look at our water sample. If you look carefully, you'll notice that the water has changed color from invisible to brown.7:40What we have produced is imbenzylamine nitrotamine, more commonly known as whiskey.7:49Whiskey is a pleasant tasting, thirst quenching drink, and it's enjoyed by all.7:56Now let's rejoin the ants and see how they're settling into their igloo.8:05A change has taken place. The igloo appears to have melted.8:11Perhaps the scientist forgot to turn off a bunsen.8:17Water, water, what hast thou donest?8:25Bless you, ants.8:28Blance.8:33Now hand in your copy book to your teacher or head of class.8:38In the next program, we will look at romance.
